SPEUIFIGATION forming part of Letters Patent No. 757,693, dated April19, 1904:. Application filed July 29, 1903. Burial No, 167,388. ('Nospecimens-l .To all whom it may courier:

' Be it known that 1, 5mm; TOLLNER, ncitizen of Austriaiiungnry,residing at New York. in the county of New York and State of New York,have invented oerluiu new and useful improvements in Blasting l ompounds. of which. the allowing u specification.

This invention relates to blasting compounds.

The object of the invention 110 produce 2i blasting compound which shallhe prnctionlly non-exploivo exceptundor ,nrossuro, hii-h shall notreadily ignite, and which when burned in confinement produros large.rolumen of gas which are developed slowly and which act with greatpressure to rupture masses of rock, cool, 8:50., Whon'properly planedand lg; niiod in a blast.

My invention consishs in the compound Whioh 1 shall now dosoriho.

I take nitrate, oi potash, upprmimntely liiteen per contain by weight,who of soda, say, thirty per contain; uni. iiftoen per oentuni; spenttunhnrli, liu'oniy per cranium. The-so ingredionts are p 'ili'orizedwhile in a dry state. l mice of horse-manure, preferably fresh, (or ifdry then moistened to a pushy consistenoyg) l/\v'% 'l;L-y per cent, andthoroughly incorporate, may, or grind" toga-finer All thosniii-grodionts. Tho moiniulfi of the horsornunure produoos with the otheringradients u pasty compourul which will not explode under ordinaryconditions while mixinn", and the Whole may he sufoly ground in a millor mortar. When the compound is thoroughly mixed, itshould he driwl,when it may no broken into lumps or may ho crumbled or pulverized. It isgenerally inadvisahlo to granulu-ie tho compound, as the granu- 1 lotionwould add to tho oxponr-u: without in- :rrouning tho oiiicioni'sy.

The compound who croniplotod may ,uored in barrels or other-receptacles.It is n05 very combustible and requires a strong stead fuse for itsignition.

The tzmhurk in the uhoie compound is a woody substance which is thoughtto be more slowly oomhusbilole than charcoal as commonly used ingunpowder. The mixture of nitrates of soda and of potash ia holioved togive a better result than would chi-her nitrate separately.'.l.l1eadmiximre of the various ingredients without dissolution ofsoluble mzi torial, hut in a slighLly-mostoned condition, :EVOlLlHdanger ill the compounding. Horsenianuro in its natural state generallycontains a rzonsidi-rahlo volume of gas, as may be found by chemicalanalysis, and when the ingrmlients are united as above describedblasting min mum] is produced which burns slowly, but! with great; andrelatively longoonlinuod pressure, so that by actual trial in quarriesthe oiioctivo work of this blasting powdoi' is found to be much great-orthan that,

of dynzunitli as commonly used.

What I claim is w 1. The blasting compound described, consisting ofnitrate of pot-ash, nitrate of soda, sulfur, tanlizirli, andhorse-manure, (:ombinod in about tho proportion sproiliod.

2. A composition of matter consisting ol nitrate of potash,upproximzmily lil'tovn por conlu m, nilruto of soda, :wproximutolythirty poxcont, sulfur, approxinumvly lift-won per mm, spout. tunhurlc,upproximutvly twenty por cont., and horsommmiro, upproxinuitoly twentypoi cont, mixed and incorporated .suhstuntiully as dosorihod.

ln liostimony whereof I ullix my signature in prosonoo of two\vitnossos.
